We liked the place. The apartment was very large and clean, as shown on the pictures. It is situated on a quiet street in front of an international school, within 15-20 min walk to Petchabury metro station and 30-40min walk to Sumkhumvit and 5min to the riverboat.
The check-in was very easy and we were welcome by Sheila (I think) who was very friendly and helped us settled. The other lady who acted as a "host" was not as friendly as she basically ignored us every time we would walk past her. We once asked her where we could buy an umbrella and her reply was that the previous guest lost it...
And it was her again during check-out and she didn't ask us anything nor say goodbye. Very strange, as she literally only said one-word "thanks" when I gave her the key.
Not a big deal, it is just not an apartment with a host like the other airbnb, it is a company who manage different apartments, just don't expect any help or tips. All the other staff, the other "host" and the cleaning lady, were very nice and friendly.
Overall, It is a nice place to stay in a nice neighborhood.
